The support frame comprises a top plate 7, a limit switch 9 and a guide mechanism 10. The top plate 7 is of a rectangular plate-shaped structure and is positioned below the cross beam 8, the top plate 7 is arranged on the cross beam 8 in an angle-adjustable mode, the driving mechanism 4 is an oil cylinder, a cylinder body of the oil cylinder is fixed on the lower surface of the top plate 7, the cylinder body is preferably perpendicular to the top plate 7, and the free end of a piston rod of the driving mechanism 4 is connected with the drilling machine 13. A guide mechanism 10 is fixed to the lower surface of the top plate 7 for providing support and guide for the drilling machine 13 when the driving mechanism 4 drives the drilling machine 13 to move.
In order to fix the top plate 7 on the cross beam 8 and adjust the angle of the top plate 7 as needed, the cross beam 8 of the present embodiment has a circular cross section; in addition, a plurality of connecting pieces 6 and nuts 62 (as shown in fig. 4) are further provided, the connecting pieces are of a three-section structure, the middle portion 61 is of a circular arc-shaped rod-shaped structure, and the two end portions 611 are provided with threads. The middle part 61 of the connecting piece 6 is lapped on the cross beam 8, and the two end parts 611 of the connecting piece 6 pass through the top plate 7 and are locked by nuts 62. That is, when the angle of the top plate 7 needs to be adjusted, that is, when the angles of the drilling machine 13 and the drill rod 131 need to be adjusted, the nut 62 is loosened, the top plate 7 and the connecting piece 6 are rotated to the proper positions, and then the nut 62 is tightened.

Aiming at various problems existing in the drilling and sampling process, the invention adopts the following targeted measures:
in the sampling process, workers easily shake to cause local damage to the core to be taken and uneven cross sections, and the drilling machine can stably work downwards at any angle due to the fact that the reverse torsion force generated by the drilling machine in the operation process easily threatens the safety of the workers. And secondly, the jack is used for applying force to the drilling machine, so that the labor intensity of workers is reduced.
The depth of sampling footage is set up by oneself through limit switch, causes unstability hard when avoiding the staff to look over the rig footage, causes the damage again to the rock core.
Because in the drilling sampling process, water is needed for auxiliary dust removal and drill bit protection, but the drilling speed of the drill bit is too high, so that mud splashes in the drilling sampling process, the ground is easy to wet and slide, and workers are influenced to continue to work stably, so that a nested and sealed transparent sleeve is used for interception.
In summary, the invention has the following beneficial effects:
can fix the rig and take a sample with arbitrary angle, guarantee the stability of sampling in-process, avoid the phenomenon that the cross-section is inhomogeneous to appear in the core. The drilling machine is arranged on the support, so that the probability of hurting people can be reduced, and the safety of workers is ensured.
3. The depth of footage is measured by utilizing the distance of the limit switch to the drill, and early warning is carried out according to the set size of footage, so that waste caused by overlong drill cores is avoided, and influence on the quality of the cores due to the deviation of the gravity center when personnel check footage is prevented. Even if the operator closes the valve of the drilling machine, a trace is left on the core during restarting, so that the discontinuous section phenomenon of the core is caused, the instrument is used for measuring the depth of footage, and the quality of the core is improved, and the working efficiency is improved.
The driving mechanism applies force to the drilling machine, so that enough supporting force can be provided, the labor intensity of workers is reduced, and the danger in operation is reduced.
Prevent and treat the mud from splashing, is favorable to protecting the clean and tidy of the sampling place, especially scenic spot environment, avoid the ground to wet and slippery, influence personnel's operation.
It will be appreciated by those skilled in the art that the present invention can be carried out in other embodiments without departing from the spirit or essential characteristics thereof. Accordingly, the above disclosed embodiments are illustrative in all respects, and not exclusive. All changes that come within the scope of the invention or equivalents thereto are intended to be embraced therein.
